   A LOW AMPLITUDE UPPER TROUGH WILL SHIFT EWD ACROSS MT INTO THE NRN
   PLAINS OVERNIGHT. AT THE SURFACE...AN AREA OF LOW PRESSURE WILL MOVE
   FROM SD INTO NRN MN BY AFTERNOON...WITH A COLD FRONT TRAILING SW
   INTO NWRN NEB. AHEAD OF THIS FRONT...A PLUME OF VERY WARM AND DRY
   AIR WILL EXIST FROM THE HIGH PLAINS INTO THE WRN GREAT LAKES. VERY
   STRONG WINDS AND LOW RH WILL RESULT IN CRITICAL FIRE CONDITIONS FOR
   MUCH OF THE UPPER MS VALLEY REGION.  TO THE S...STRONG WINDS AND LOW
   RH WILL PERSIST OVER THE CNTRL AND SRN HIGH PLAINS WITH A SECONDARY
   LOW OVER ERN CO.

   WI...AND THAT IS WHERE THE MOST SEVERE FIRE THREAT WILL EXIST. AREAS
   SUCH AS FAR SRN MN...SRN WI...AND POINTS S HAVE SEEN MUCH MORE
   PRECIPITATION AND FUELS ARE LIKELY NOT AS DRY. ALTHOUGH THE
   PROBABILITY OF FIRE STARTS WILL BE LESSENED WHERE FUELS ARE LESS
   DRY...EXTREME WIND GUSTS...WARM TEMPERATURES AND LOW RH CAN STILL
   RESULT IN RAPID FIRE SPREAD SHOULD FIRES OCCUR.

   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER RIDGE WILL SLOWLY SHIFT E OFF THE E COAST...WITH HIGH
   PRESSURE ACROSS THE MID ATLANTIC. THIS WILL RESULT IN CONTINUED WARM
   AND DRY WEATHER FOR THE ERN STATES...EXCEPT FOR THE GULF COAST
   REGION WHERE NUMEROUS RAIN SHOWERS WILL PERSIST DUE TO AN UPPER LOW
   OVER THE CNTRL GULF. GUSTY SW WINDS WILL STRETCH FROM MI INTO NEW

   CRITICAL FIRE CONDITIONS FOR MI AND WRN NY WHERE FUELS ARE DRIEST.
   
   ELSEWHERE...ZONAL FLOW WILL HUG THE U.S./CANADIAN BORDER WITH A WEAK
   UPPER RIDGE ACROSS THE SWRN STATES. AFTERNOON THUNDERSTORMS WILL BE
   COMMON OVER UT/CO/AZ AND NM...WITH SOME DRY.

   SW WINDS OF 15-25 MPH WITH HIGHER GUSTS WILL OCCUR UNDER A
   FLATTENING UPPER RIDGE. HIGH TEMPERATURES WILL AVERAGE IN THE 80S
   WITH MIN RH IN THE 25-35 PERCENT RANGE. THIS MAY RESULT IN
